Krell stuff is amazing. I know a guy who repairs amps (works) for Krell. They paid him enough that he shut down his repair shop of 20 years and went to work for them.
I have made my own speakers and they sound better than anything I could ever afford. The lasy pair of electrostatics where the best sounding and the pair of 1/4 wave tubes I built also sound great. The electrostatics costs my about $500 to build but sound as good as Martin Logans IMO for fr less money.
Krell is dreamland stuff for the plebiscite.
